Cervical Cancer Cell Image Database: Multi-focus Cytology Dataset (CCCID)

This dataset contains cervical cytology cell images classified into four diagnostic categories according to the Bethesda System: NILM (Negative for Intraepithelial Lesion or Malignancy), LSIL (Low-grade Squamous Intraepithelial Lesion), HSIL (High-grade Squamous Intraepithelial Lesion), and SCC/others (Squamous Cell Carcinoma and other malignancies). The images were obtained from Papanicolaou-stained cervical cytology specimens and digitized using a slide scanner. Each cell image is provided as an 11-layer multi-focus image stack with a focus interval of 1 μm. This database was developed as part of the JST-CREST research project "Construction of an Innovative Cancer Diagnosis Support System Using 3D Image Recognition AI" and organized by the Cervical Cancer Cell Image Database Project (CCCID-Project).
